Launch the app and log in with your Mercedes me account. Follow the in-app instructions.

Step 3: insert Adapter

Insert the Adapter into your vehicle's diagnostic socket ("OBD2 socket"). You can use the supplied fastenings (sticker with Velcro fastener) to fasten the flap on the Adapter. The red LED on the Adapter then starts flashing.

Step 4: pair Adapter and smartphone via Bluetooth®

You can connect your smartphone to the Adapter via Bluetooth® within the next three minutes. To do this, search for the device with the name "MB..." in your smartphone's Bluetooth® menu. The LED lights constantly if your vehicle is paired with the Adapter. Repeat the process if it takes more than three minutes.

Step 5: launch app

Then launch the app on your smartphone, log in with your Mercedes me user account if necessary, and select "Add new vehicle". Ensure that you have a stable internet connection. If you have already defined a vehicle in the app, activate "My vehicle" and select "Add another vehicle".

Step 6: start engine

Now start your vehicle's engine to complete the installation when prompted to do so in the app. The vehicle data will then be determined and checked, and your preferred service partner saved on the Mercedes me Portal is copied to the app. Follow the in-app instructions until activation is complete. When prompted to do so in the app, switch off the engine and confirm that activation is complete.

Your vehicle has now been defined successfully, and you can use all of the Mercedes me Adapter functions.
